Ashlee Simpson revealed more than she planned to at the Throwback Thursday Bash at El Lay's Pink Taco last night.

The party theme was the 90s, but the 28-year-old paid homage to the renowned flashers of the last decade (Paris Hilton, Britney Spears, to name a few) as she climbed into the backseat of her ride and accidentally flashed her own pink taco!

She's been keeping a low-profile lately, but this is guaranteed to put her back in spotlight, at least for a few minutes!
